Solution: Add Strings
Explore how to add two non-negative integers given as strings by simulating manual digit-by-digit addition without converting them directly to integers. Learn to handle carries and understand the algorithm's time and space complexity. This lesson helps you accurately sum large numbers when built-in big integer tools are not allowed.

Statement
Given two non-negative integers, num1 and num2, represented as strings, return the sum of num1 and num2 as a string.
You must not use any built-in library for handling large integers (such as BigInteger) or directly convert the inputs to integers.
